A critical differences between SRX882 and SRX882s is:
- On the SRX882 the CS pin can be disconnected or connected to VCC.
- On the SRX882s the CS pin must be connected to VCC. The SRX882s is in sleep mode without it!

@1technophile I think it is essential to update the documentation with this distinction because I think that the current documentation is wrong and cannot work with SRX882s.
